BENJAMIN BRIDENDOLPH, OF CLEAR SPRING, MARYLAND.

HOMINY-MIIJL.

Specification of Letters Patent No. 11,547, dated August 22, 1854.

- To all whom it may concern Be it known that I, BENJAMIN BRIDEN- DOLPH, of Clear Spring, in the county of WVashington and State of Maryland, have invented a new and useful Improvement in Hominy-Mills; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the anneXed drawings, forming part of this specifloat-ion, in which-- Figure 1 is a vertical section of the mill,

I taken through the axis of the hulling shaft,

I volved within a roughened cylinder and by the action of the two series of spirals upon the corn, effectually stripping the grains of hulls and eyes, and breaking the same to the required size, in the manner hereafter to be described.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.

In the drawing A is the cylindersupported by the frame B and having its interior surface made up of the small pyramidal projections 0 so as to present a roughened surface with innumerable sallent edges,

disposed in the best manner for assisting in the strippin and breaking operation. The

- hulling shaft C is of the form shown in bevel wheels 71, and z.

Fig. 2, having the hollow spiral faces d meeting along edges, across which run the spirals f in the reverse direction from the main spirals cl. This shaft rests in the bot tom of the cylinder A, and is revolved by power applied to the shaft e through the In the bottom of the cylinder A is the sliding door m through which the hominy issues to the 'screen S where it is cleaned of hulls and other light impurities by the fan a.

The operation of my improved hominy mill is as follows: The corn is fed to the machine by the hopperII and motion communicated to the shaft C as above described. A band around the pulley P and fan shaft gives motion to the fan, and reciprocates the sieve 3 through the rods t and a, and crank 41. The spring door We. is kept closed at first and opened but slightly after the operation has progressed, for the passage of the finished hominy. The main spirals d of the hulling shaft, tend by the revolution of the shaft to pack the corn in a mass toward the bottom of the cylinder; while the reverse spirals f on the edges, catch the downward pressed grain, and draw it upward against the roughened interior of the cylinder, causing a severe cutting friction sufficient to strip off the hulls, remove the eyes, and break the grain. The main spirals (I having a greater action than the secondary spirals f, the corn is always crowded in a mass to the bottom of the cylinder, and is always in asituation to receive the reverse action of the spirals The door 71?. is opened slightly, so that the finished hominy shall pass out slowly and not prevent the packing of the mass in the bottom of the cylinder. After leaving the cylinder, the fan and screen separate, the impurities in the ordinary manner.

The important feature of this mill is the compound spiral hulling shaft, the main spirals of which pack the body of the corn sufficiently hard for the reverse spirals to effectually act upon, and by the aid of the roughened concave to break and strip the grain.

What I claim as my invention and desire to secure by Letters Patent, is

The compound spiral hulling shaft constructed as herein described, and operating in connection with a roughened concave for hulling and breaking corn substantially as specified.

In testimony whereof, I have hereunto signed my name before, two subscribing witnesses.
